Network requirements for VM migration
I am trying to setup a RHEV3 system with 4 HP DL380 G7 servers ( 2 for manager and 2 for hypervisor ) connected to a iscsi RAID. Each RHEV-H server comes with four 1g nics. I plan to use 2 bonded ( active/standby ) networks, one for iscsi-storage and another for data traffic. On the traffic bond network, I also plan to have dedicated VLANs for management and traffic. One thing i didn't find more detail is how VM migration is handled.
Is there any pointers on how much bandwidth is needed for VM migration? Also when a VM is migrated what is the role of the RHEV-M in the migration. Does the migration traffic go peer to peer or gets proxied via RHEV-M?
thanks
Ramesh
